Expected Functionality:
We expect to be able to apply up to 60V DC input and regulate out to +12V using the LT8390

Issue:
When voltages > 17.5V are applied to the input (+VBATT), the output of the LT8390 begins to oscillate. At input voltages < 17.5V the…

Hi,

I am trying to simulate the LT8390 using LTSPICE, however I want to use a solar panel as an input. I managed to simulate a solar cell, however I cant use it as an input into the LT8390 model. I am trying to model and simulate the scenario on page…

1.在输入12V，输出12V，100W的应用中，MOS管尤其是TG1和BG2端的MOS管发热大，50，60度（推荐的MOS型号，内阻以及Qg均不大），有没有什么建议和解决方法

2.若MOS管并联有什么要求

Hello.

I have a problem with the LT8390, I use it as a solar charger with a lead acid battery 12V.

I use your application circuit showing a solar panel charger in datasheet page 32.

The layout is made as specified in datasheet.

The FB circuit is a little…

Hi all,

I'm using ic LT8390 in buck region with: Input 36V (This value is output voltage of ic LT8705) and output which I need is 24V. But, output voltage of LT8390 is oscilated, and volatage value is not 24V. If I use input is lower 30V, output voltage…

Use LT8390 to make a 24V input, 12V/25A output power supply, encountered some problems during debugging

Adjust the output current up to 8A, more than 8A for a while, the inductor will emit a noise, the circuit at this time no output.

1. My inductor model…

Hi,

I am trying to simulate the LT8390 using LTSPICE, I am trying to model and simulate the scenario on page 32 of the LT8390 data sheet (125 W Solar panel to 12V battery charger). I have built the model as per the datasheet, I used a voltage source as…
